Treating tanalised timber

[colin H]

Hello Folks ,

I recently bought a wooden corner seat/arbour for my garden . My idea was to treat it using liberon decking oil - as Ive used on my decking .

However , when i started staining it , I can still see the green spots coming through in places caused by the tanalith . I tried sanding it , but its hard to remove .

Do you think I would be better off building it first , and leaving it outside to weather first , or will the green stuff go in time anyway ?

the treatment is still wet and will continue to ooze out to a certain degree, you need to leave any tanalised timber at least 6 weeks from treatment for it to dry out a little.

Somtimes it has been done a few weeks before sale sometimes a day. so it can be a lottery.

Best thing now is to leave it to dry out and then re-oil it in 6 or 8 weeks

Ive actually had the timber in my garrage for around 3 months - I bought it in the sales . Its dry but the tanalith is still present on the surface

Oh dear in that case i'm very surprised that has happened?

I can only guess that the oil has dampened patches of the treatment and sort of re-activated it bringing it to the surface but thats just a thought i don't really know what is happening exactly.

Is it mainly around knots or all over the timber?
